On the Simplex-based Methods for Neutrosophic Linear Programming Problems Sulima Ahmed Mohammed Zubair, Najla ELzein AbuKaswi Osman, Wiem Abedelmonem Salah Ben Khalifa, Amal Hassan Mohammed Yassin Journal of Fuzzy Extension and Applications, 2024 This paper investigates Neutrosophic Linear Programming (NLP) and focuses on one of the most suitable approaches to solve it, which is called the Simplex-based model. This type of method, inspired by the classic Simplex algorithm, is in search of an optimal basic neutrosophic feasible solution, and several attractive models of it have been proposed in recent years. However, due to neutrosophic logic considers three dimensions of a problem, using a direct generalization of the simplex algorithm (which has been done in existing methods), the computational volume is greatly increased even for the small problems, and as a result, the use of these models in real-world issues will be questioned. To solve this gap, we consider NLP and propose an effective, simple model that can significantly reduce computational tasks and address these deficits in the mentioned models. Some numerical experiments with the comparison results are provided to explain the efficiency and superiority of the proposed approach.
A new strict decay rate for systems of longitudinal m-nonlinear viscoelastic wave equations Keltoum Bouhali, Sulima Ahmed Zubair, Wiem Abedelmonem Salah Ben Khalifa, Najla ELzein AbuKaswi Osman, Khaled Zennir Aims Mathematics, 2023 <abstract><p>Recent years have been marked by a significant increase in interest in solving nonlinear equations that arise in various fields of natural science. This trend is associated with the creation of a new method of mathematical physics. The present study is devoted to the analysis of the propagation of $ m $-nonlinear viscoelastic waves equations in an unbounded domain. The physical properties are determined by the equations of the linear theory of viscoelasticity. This article shows the main effect and interaction between the different weak and strong damping terms on the behavior of solutions. We found, under a novel condition on the kernel functions, an energy decay rate by using an appropriate energy estimates.</p></abstract>
CLASSICAL SOLUTIONS FOR A BVP FOR A CLASS IMPULSIVE FRACTIONAL PARTIAL DIFFERENTIAL EQUATIONS SVETLIN G. GEORGIEV, KHALED ZENNIR, WIEM ABEDELMONEM SALAH BEN KHALIFA, AMAL HASSAN MOHAMMED YASSIN, AYMEN GHILEN, SULIMA AHMED MOHAMMED ZUBAIR, NAJLA ELZEIN ABUKASWI OSMAN Fractals, 2022 In this paper, we investigate a BVP for a class impulsive fractional partial differential equations. We propose a new topological approach to prove the existence of at least one classical solution and at least two nonnegative classical solutions. The arguments are based upon recent theoretical results.
Quantum cryptography for the benefit of API keys safety Aymen Ramadhan Ghilen, Amel Mohamed Zahou, Wiem Abedelmonem Ben Khalifa 2022 IEEE 9th International Conference on Sciences of Electronics Technologies of Information and Telecommunications Setit 2022, 2022 To cope with the unauthorized access to the cloud treasure of resources and services, several cloud service providers implement the API-based access control approach and grant thus a full authentication of any client application. Once called, each cloud API (Application Programming Interface) is required to authenticate through a secret access key, commonly termed API key. A plethora of security risks is associated with these keys whether during their generation, storage, or utilization. The hardware secure element-based proposal aims for an end-to-end security between a cloud service provider and a client application. To ensure a reliable and secure API key exchange, the concerned entities rely on Public Key Infrastructure (PKI). As soon as an adversary acquires an unbounded computing power, it would be easy to intercept the keys and then unlock the gate behind the valuables over the cloud. In this paper, we propose a revised scheme that discards the PKI and installs a quantum mechanism to mutually authenticate the secure element and the cloud service provider by establishing a set of shared keys. A pioneering absolute security of the presented approach is warranted by the principles of quantum physics. To analyze the security of the quantum technology, we establish a formal verification based on PRISM model checking tool. We outstandingly focus on satisfying two prominent properties: (i) both the parties engaged in the quantum protocol are able to detect any disallowed eavesdropping and (ii) the valid amount of information caught by an adversary on the installed key must be negligible.
An Application for Measuring and Analyzing the Level of Performance Accuracy for Health Services Quality Indicators by Using Six-Sigma: A Study Case of Government Hospitals in Khartoum State Amal Hassan Mohammed Yassin, Najla Elzein Abukassawi Osman, Wiem Abedelmonem Ben Khalifa, Eltahir Nouh Mohammed Adam Journal of Healthcare Engineering, 2021 The study aimed at acknowledging the Six Sigma methodology and the existence of the essential components for the application, as well as reducing the time for completing the operations, reducing the error rate to the lowest possible level, and improving the quality of operations. For this objective, the analytical descriptive methodology was used on a sample consisted of 300 administrative and medical staff from Khartoum State Hospitals (Khartoum, Omdurman, Bahri). To this end, a questionnaire was used for collecting data and for analyzing it and achieving the results of the study by using the statistical analysis package (SPSS). The study deduced a number of results, the most important of which are that the items of commitment and supreme command support for the senior leadership and the methods of abundant human resources on quality control, and the application of the Six Sigma methodology in government hospitals in Khartoum state achieved a satisfactory level, while continuous improvement paragraphs, processes, and systems on quality control and the application of Six Sigma methodology achieved high quality. There is a significant effect on the extent of commitment and support of the higher leadership on quality control and the application of the Six Sigma methodology. Similarly, there is a statistically significant effect on the application of continuous improvement methods on quality control and Six Sigma methodology. Also, there is a statistically significant effect on the application of the abundance of human resources methods variable on quality control and the application of Six Sigma methodology in governmental hospitals in Khartoum state. The study recommended to take interest in the Six Sigma methodology and assure the possibility of using it in Khartoum State’s hospitals because of its scientific and practical importance in improving the quality of services and provided processes, and the need to provide qualified financial and human resources for using and developing Six Sigma methodology in hospitals, as well as great attention in training and providing departments heads with full knowledge of Six Sigma methodology and the fundamentals on which Six Sigma methodology, is based on its importance for hospitals. The study also recommended associating the promotions system in government hospitals in Khartoum state with the quality control program.
Organizational Citizenship Behavior and Resonant Leadership, Analyzing Mediation Effect of Employee Resilience in Saudi Arabian Companies SARDAR ZAFAR IQBAL, ALBANDARY MOHAMMED ALAMER, HINA GULL, WIEM ABDALMONEM BIN KHALEFA ACM International Conference Proceeding Series, 2020 As the concept of organizational behavior has been introduced several years ago, but its standing in achieving completive advantage for an organization is still of great importance. So, organizations are paying more consideration to positive organizational behavior and its underlying factors that affect organizations. In this paper, we have analyzed the relationship between resonant leadership and organizational behavior and the mediation effect of employee resilience on organizational behavior in companies of Saudi Arabia. This paper is based on a cross-sectional survey in public and private sector organizations in Saudi Arabia. The results suggest that in Saudi Arabian organizations there is a negative relationship between resonant leadership and organizational behavior. On the other hand, they have positive and strong meditation effect of employee resilience.

The proposed method is based on a combination of data presentation and a conceptual map of ontologies. The proposed method is based on the following steps: Process the text of the student's response by removing the stop words and sound from the text. Extract information about the student's response and plan in the form of a conceptual table; comparison between the reference and the student's response and assignment of points by semantic proportions; the score is calculated on the basis of the positional similarity of the measurement results.
E-assessment system for open and short answer (applied to a course of Arabic grammar in 7th year in Tunisia) Wiem Ben Khalifa, Dalila Souilem, Mahmoud Neji International Journal of Online Pedagogy and Course Design, 2018 The goal of this article is the development of an evaluation system based on the Arabic language. This article contains four parts. The first part is the corpus construction from the 7th year basic education classes' grammar book in Tunisia. Then, the second part is on the construction of the Concept Maps (CMaps) ontological for simple Arabic sentences from this corpus, where the automatic extraction of terms is completed. This extraction is based on two major approaches: linguistic and statistical. The third part in this article is the automatic instantiation. The last part is devoted to the application of the similarity measure chosen in the CMaps ontological fusion, which summarizes the various semantic links and which ends with a judgment according to the calculated score.
